NASHVILLE, Tenn. -- Titans rookie running back Derrick Henry had an MRI that confirmed that his left calf injury is a strain.
"That's kind of an injury that a lot of it is pain tolerance," coach Mike Mularkey said Monday. "It could be a day up to a couple weeks. We'll monitor that as we go."
Henry suffered the injury during warm-ups Sunday and did not play in a 43-35 loss to the Chargers.
If Henry doesn't play Sunday against the Green Bay Packers at Nissan Stadium, the Titans will look to Antonio Andrews behind DeMarco Murray. Andrews got two carries for 15 yards against the Chargers.
On Monday, the Titans promoted running back David Fluellen from their practice squad and waived cornerback Cody Riggs.
Henry, the Heisman Trophy winner from Alabama, is second on the Titans with 53 carries, but his 221 yards and 4.2 yards per carry rank behind Murray and quarterback Marcus Mariota.
The Titans have used Murray heavily, and Mularkey consistently says Henry's role is determined by game flow. He has maxed out at 16 carries in a game but has averaged fewer than seven per game while Murray gets just over 19.
