Seattle Seahawks receiver Ricardo Lockette is "up and walking" after undergoing surgery for ligament damage in his neck this week ... this according to Ricardo's dad.
Lockette was carted off the field on Sunday after taking a devastating blow from Dallas Cowboys safety Jeff Heath. He was diagnosed with a concussion, suffered disk and ligament damage and will not play again this season.
The 29-year-old underwent surgery the next day at Baylor University -- and now, his father Earl Lockette tells TMZ Sports he's well on the road to recovery.
"Ricardo is up and walking. He's really energetic and looking forward to rehab as the next step."
"The family is extremely grateful for all the prayers and support from people around the country. Also, thank you to the press for the positive concern."
