Mike Florio of ProFootballTalk.com reports that an MRI has confirmed that Oakland Raiders cornerback Nnamdi Asomugha has a high right ankle sprain.
Asomugha will seek a second opinion, PFT adds.
The All-Pro cornerback was injured while covering Seattle Seahawks rookie wide receiver Golden Tate on a sideline play in the 4th quarter of the Raiders' 33-3 win on Sunday. The Raiders were already playing without starting cornerback Chris Johnson, who missed yesterday's game with a concussion, prompting safety Michael Huff to play cornerback.
Johnson could return for next week's game against the Kansas City Chiefs.
"I firmly believe that any man’s finest hour, the greatest fulfillment of all that he holds dear, is that moment when he has worked his heart out in a good cause and lies exhausted on the field of battle – victorious."
