SANTA CLARA, Calif. — After losing Braylon Edwards to a knee injury that required surgery in Week 2, the 49ers are down another star wideout heading into a key game Sunday at unbeaten Detroit.
Joshua Morgan is done for the season with a broken bone in his lower right leg. He had surgery Monday and had screws inserted to stabilize the injury, which coach Jim Harbaugh said isn't career-threatening.
San Francisco placed Morgan on the season-ending injured reserve list Wednesday after he was hurt late in a 48-3 victory against the Buccaneers on Sunday. To help fill the void, the Niners signed Brett Swain to a one-year deal.
Morgan, 26, a fourth-year pro out of Virginia Tech, had 15 catches for 220 yards and one touchdown for the 49ers this year. Five catches came in the rout of the Bucs.
"His career will be fine," Harbaugh said. "We'll give him the time to really get it healed right."
BROWNS LOSE DE: Defensive end Marcus Benard is out for the season with a broken hand sustained when he crashed his three-wheel motorcycle on Monday. Benard, who was Cleveland's sack leader last season, went on the reserve non-football injury list.
