The Bee's Matthew Barrows highlights six players to watch tonight against the San Diego Chargers:
No. 5, B.J. DANIELS, QB
The seventh-round pick has looked sharp in his last two outings, and there's no doubt the 49ers want to keep him. The only question is whether it's on the active roster or practice squad. A third strong performance might eliminate the practice squad as an option; Daniels would have to pass through waivers to land there.
No. 18, SENECA WALLACE, QB
With the first two quarterback spots seemingly set, Wallace should see a lot of work against the Chargers. That would be his preference. The newcomer needs to get on film as much as possible in case the 49ers decide they had their top three quarterbacks all along. Wallace also is auditioning for 31 other squads.
No. 6, AUSTIN COLLIE, WR
The El Dorado Hills product may not be among the five receivers the team plans to keep, but he's proving to other receiver-needy teams that he is healthy after last year's knee injury. Collie didn't enter Sunday's game until 20 seconds remained in the third quarter. He's hoping for an earlier entrance against the Chargers.
No. 50, CAM JOHNSON, OLB
The trade that sent Parys Haralson to New Orleans was a boon for Johnson. The second-year player remains on the roster bubble, but he's been making steady progress and the 49ers could find a spot for him on the 53-man squad. Johnson needs to make a bigger mark on special teams.
No. 63, TONY JEROD-EDDIE, DE
The left defensive end's only publicity this preseason came when he hit Chiefs quarterback Alex Smith and was flagged for a personal foul. Jerod-Eddie, however, has had a strong offseason and is in the conversation with Demarcus Dobbs and Will Tukuafu for a backup spot.
No. 47, KEVIN McDERMOTT, LS
The closest roster battle? If you believe 49ers coach Jim Harbaugh, it's at long snapper, where McDermott, a rookie, is trying to unseat 13-year veteran Brian Jennings. Jennings took the first snap Sunday against Minnesota; McDermott handled the rest, and not a single one was out of place.
