SANTA CLARA When the 49ers signed Austin Collie and Lavelle Hawkins on Aug. 2, their wide-receiving corps was in tatters. They needed bodies at the position. Even quarterback B.J. Daniels was taking repetitions at wideout to help the team get through an afternoon practice.
Two days later, however, four of the team's injured wide receivers were back, and the 49ers suddenly had a full house.
The question now is whether Collie and Hawkins had enough time and enough snaps to impress a coaching staff that must cut 15 players Tuesday and trim the roster to 53 on Aug. 31.
Collie said he'd like more opportunities but stopped short of saying he was frustrated by the situation.
"If you don't want to be on the field all the time, there's something wrong with you," he said. "That's the nature of the beast being a wide receiver. That's the nature of the beast being a football player."
Collie, who played at Oak Ridge High, started cautiously after joining the 49ers. He had been out of action since October while recovering from a patellar tendon tear when he was with the Colts. He reported steady progress over the last three weeks and said he feels like he's back to normal.
"My knee's 100 percent as far as healing, as far as being ready to go," Collie said this week. "But for anyone who didn't take part in OTAs or have offseason training or anything like that, anyone who sat out that long 10 months it takes time."
In an attempt to accelerate A.J. Jenkins' progress, the 49ers gave him a lot of practice repetitions and more snaps in the preseason than any other receiver. Jenkins was traded to Kansas City on Monday, and the 49ers obtained another receiver, Jon Baldwin, in the move.
Asked whether the three newcomers Collie, Hawkins and Baldwin would get extra snaps Sunday against Minnesota, coach Jim Harbaugh said, "I sure would like to. They're very competitive guys and they want them. There's quite a few receivers that we have that are all healthy and champing at the bit to get them. Hopefully that works out that way this week, that our receivers all get a real good look."
After the 49ers cut Ricardo Lockette on Thursday, they still have 10 healthy wide receivers on the active roster. Kyle Williams said he was ready to play after missing the first two preseason games.
Et cetera Harbaugh confirmed that rookie running back Marcus Lattimore (knee) would begin the season on the non-football injury list. Lattimore is not expected to play in 2013.
Harbaugh called the long-snapping competition between 13-year veteran Brian Jennings and rookie Kevin McDermott "very, very close." Jennings was brought in for a key snap Friday when the 49ers were backed up against their own goal; the snap and punt by rookie Colton Schmidt were perfect.
Defensive end Tony Jerod-Eddie did not get fined for a helmet-to-helmet hit on quarterback Alex Smith during last week's victory over the Chiefs. Jerod-Eddie was penalized for unsportsmanlike conduct.
