The 49ers on Monday waived veteran Nnamdi Asomugha, who lost his role as the No. 3 cornerback to Tramaine Brock after three games, a league source said.
Asomugha, 32, who signed a one-year, $1.35 million contract in April, won a roster spot with the 49ers to open the season. However, when he was forced out of the lineup due to a knee injury, he was not able to regain his role as the third cornerback.
Asomugha is subject to the waivers system. If he goes unclaimed, the 49ers will owe him the remainder of his salary for the season.
Asomugha is in his 11th NFL season. After eight strong seasons with the Raiders, he signed a lucrative contract with the Philadelphia Eagles. After two disappointing seasons, he was released.
The removal of Asomugha from the 49ers’ 53-man roster opens a roster spot for cornerback Eric Wright, who the 49ers will activate off the reserve/non-football illness list.
