(TSX / STATS) -- Baltimore Ravens running back Danny Woodhead is expected to be out at least four weeks and might miss eight weeks with a hamstring injury, multiple outlets reported Tuesday.

The NFL Network reported Woodhead would miss four to six weeks, while ESPN said he would be sidelined for six to eight weeks.

Woodhead missed time in the preseason due to the same ailment. He was re-injured Sunday during the opening drive of Baltimore's 20-0 win over the Cincinnati Bengals. Woodhead caught three passes for 33 yards and rushed once for 4 yards before exiting.

Woodhead, 32, signed with Baltimore during the first day of free agency in March to serve as a complement to Terrance West with his abilities to catch passes out of the backfield. The Ravens reportedly gave him a three-year deal worth $8.8 million, with $4.25 million guaranteed after Woodhead missed most of last season with the San Diego Chargers due to a torn anterior cruciate ligament in his right knee.

It is the second straight season Woodhead was injured in the opening weeks. In 2016, he tore his ACL in Week 2 against the Jacksonville Jaguars.

Woodhead also sustained a season-ending broken leg early in the 2014 season with San Diego.

In 94 regular-season games for the New York Jets, New England Patriots, San Diego and Baltimore, he has 2,186 rushing yards on 15 touchdowns to go along with 2,531 receiving yards and 17 receiving TDs.
