The Minnesota Vikings have confirmed Adrian Peterson has not suffered ligament damage in his right knee, after the star running back underwent surgery to fix his torn meniscus.
Doctors on Thursday successfully repaired the lateral meniscus in Peterson's knee, the team announced.
Rumours had suggested that Peterson had suffered torn ligament damage after going down during his side's 17-14 win over the Green Bay Packers on Sunday, extending their unbeaten start to the season.
However, the team confirmed that he has suffered just one injury, significantly boosting his chances of returning to the field later in 2016.
The Vikings have already lost starting quarterback Teddy Bridgewater to a season-ending knee injury, but Sam Bradford filled the void superbly, throwing 22/31 for 286 yards and two touchdowns against the Packers.
