SANTA CLARA, Calif. -- The San Francisco 49ers promoted rookie cornerback Darryl Morris from the practice squad to the 53-man roster. It is an indication No. 3 cornerback Nnamdi Asomugha may not be ready to play Thursday at St Louis.
Asomugha suffered a leg injury in the loss to the Colts on Sunday.
Morris is an undrafted free agent from Texas State. He takes the roster spot that was created when the 49ers put star pass-rusher Aldon Smith on the reserve/non-football illness list. Smith has entered a rehabilitation center for alcohol abuse. He is expected to be away from the team for about a week.
To fill Morris’ spot on the practice squad, the 49ers signed former Minnesota defensive end D'Aundre Reed to the practice squad. They worked him out Monday. He is developmental player who could be an interesting fit in a 3-4 team.
In other 49ers’ news:
Running back Frank Gore told reporters he is fine with coach Jim Harbaugh and disputed a report that he yelled at the coach during the loss to the Colts on Sunday.
Safety Donte Whitner told the Associated Press the NFL called Monday to say his penalty on the first offensive play against the Colts should not have been called. Whitner was called for hitting with the crown of his helmet. Replays showed Whitner led with his shoulder. The play sparked a touchdown drive for the Colts.
The 49ers-Seahawks pipeline continued. The Seahawks worked out defensive tackle Will Tukuafu. He was recently cut by the 49ers.
