Chargers head coach Jim Harbaugh said Palmer (foot) isn't in line to practice Tuesday, Daniel Popper of The Athletic reports.
After exiting the Chargers' Week 17 win over the Patriots with a foot injury, Palmer didn't practice in any fashion last week before sitting out a 34-20 win over the Raiders in the regular-season finale, and he's yet to take any tangible steps forward in his recovery as the Chargers begin prepping for Saturday's wild-card game in Houston. In Palmer's absence in Week 18, DJ Chark stepped in as the Chargers' No. 3 wideout and finished with a six-yard touchdown reception across three targets.
