SANTA CLARA, Calif. - Earlier this week, the San Francisco 49ers traded for slot receiver/returner Jeremy Kerley. On Tuesday, the reason for that move became clear as the team placed presumptive starting slot receiver Bruce Ellington on injured reserve with a hamstring injury.Ellington suffered the injury last week in the Niners third preseason game against the Green Bay Packers. It happened on a punt return as Ellington stumbled forward to catch the punt before falling awkwardly. He limped off the field and spent most of the first half on the bench with a towel over his head. San Francisco coach Chip Kelly said Ellington had an MRI on Saturday. Ellington is not eligible for the injured reserve/designated to return tag because he was not on the 53-man roster when the preseason ended.Ellingtons two-year career has been marred by various injuries that cost him six games. The 2014 fourth-round pick out of South Carolina has 19 catches for 215 yards and two touchdowns while also serving as the primary returner over two seasons.Kerley, who came in a deal for offensive lineman Brandon Thomas with the Detroit Lions, is expected to help fill both voids.Jeremy gives us some depth as a slot receiver, offensive coordinator Curtis Modkins said. Hes played a lot of football in this league as a slot. He also gives us some versatility as a returner, so hes added depth that we really need and I think hell be able to get caught up to speed fairly quickly.The 49ers also released linebacker Jason Fanaika to get to the league-mandated 75-man roster before Tuesdays deadline.

Uncertainty over Shaun Marshs badly broken finger has ensured that Australias revamped Test squad was retained for the first Test against Pakistan at the Gabba.The selectors had made sweeping changes after Australias crushing defeat in Hobart, where South Africa secured the series, and only six of the XI from that Test retained their places for the day-night Test in Adelaide. Matt Renshaw, Peter Handscomb and Nic Maddinson all made their debuts in Adelaide, where Australia picked up a consolation victory.Maddinson, who made 80 in a Sheffield Shield match for New South Wales this week, was thought he man most likely to make way in the event of Marsh returning to fitness. However Marsh was not considered as he continues rehabilitation after a broken finger suffered against South Africa in Perth.Shaun has yet to resume batting and will have a follow-up x-ray this week that will be reviewed by a specialist, the CA head of sports science Alex Kountouris said. This will determine when he can resume cricket training.It is believed that Marshs finger injury, a re-break suffered during the first Test after he initially fractured it in Sri Lanka, is of a more serious nature than initially thought. Australias coach Darren Lehmann conceded that Marsh would now need to prove his fitness via the Big Bash League - either for the Pakistan series or the tour of India next year, for which he is considered a vital component given a sound batting method against spin.Fingers crossed. Hopefully hell be batting soon, the specialist will be seeing him this week and hopefully that goes well and he starts batting again, Lehmann said. Hes only got BBL to play. If he plays that and gets through hell be available for selection.Usman Khawaja did it last year, he had a BBL game from a hamstring and thats all we had to go on. As long as they can get through then theyre available.Lehmann also said Marsh would be able to slot into a middle order role when fit, despite most recently playing as an opener alongside David Warner.dddddddddddd He did really well in Perth in the Test match for us opening, he scored a hundred for us opening but hes had success down the order as well, Lehmann said. Hes one of those guys who can fit in anywhere in the top six which is pleasing to have. It depends on what happens with other positions.The Gabba Test is also a day-night affair, and given Australias success in Adelaide and the desire for stability, there is every chance they will take an unchanged XI into a Test for the first time in more than a year. The only possible alteration would be if Adelaide 12th man Chadd Sayers came into contention, and he did his chances no harm by taking eight wickets in the Sheffield Shield this week.We were very pleased with how the team came together in Adelaide after some significant changes following the Tests in Perth and Hobart, the interim selection chairman Trevor Hohns said. This is a young group with a lot of promise and we believe all deserve their opportunity again in this upcoming Test.Of Australias debutants from the previous match, Maddinson in particular will be keen to prove his Test worth at the Gabba, having fallen for a 12-ball duck in his only innings of the Adelaide Test. Maddinson bounced back from that disappointment with 80 in the first innings for New South Wales this week in their Shield game against South Australia.The other Adelaide debutants, Handscomb and Renshaw, both enjoyed longer stays at the crease in their first appearance for Australia. Handscomb scored a half-century in the first innings and then hit the winning runs in the second, while Renshaw occupied the crease for 137 balls in Australias chase to help them secure victory.Squad David Warner, Matt Renshaw, Usman Khawaja, Steven Smith (capt), Peter Handscomb, Nic Maddinson, Matthew Wade (wk), Mitchell Starc, Josh Hazlewood, Nathan Lyon, Jackson Bird, Chadd Sayers.
