The Minnesota Vikings have been without the services of starting quarterback Sam Bradford for the last few weeks due to a nagging knee injury.

However, the 29-year-old finally returned to the practice field on Thursday afternoon, according to the Vikings Official Twitter account.

Bradford has been sidelined for the last three games due to a non-contact injury to his left knee that occurred during the Week 1 win over the New Orleans Saints. He last took the practice field on Sept 21. prior to getting a second opinion from Dr. James Andrews. The examination revealed that there was no structural damage to the area.

The former first overall pick of the 2010 NFL Draft has a long history with leg injuries, as he has suffered a pair of ACL tears playing for the then-St. Louis Rams. The Week 1 performance against the Saints was arguably the best of his NFL career, as he completed 27 of 32 passes for 346 yards and three touchdowns, good for a 143.0 passer rating and a 95.2 quarterback rating (QBR). In his absence, the Vikings have lost two out of the last three games with backup Case Keenum under center.

Although Bradford has been able to take the practice field, there is no firm indication as to when he will make his return. Minnesota is slated to face the Chicago Bears on Monday night in Week 5.
