Chargers running back Ryan Mathews played through a high ankle sprain, according to San Diego Union-Tribune.
The typical recovery from the injury lasts four-to-six weeks, but Mathews didn't miss a game. Mathews first injured the ankle December 22 against Oakland, but was able to return to the game. He received a normal workload the following week, so it wasn't serious initially. But the injury got worse in the playoffs, forcing Mathews to stop practicing. He had just 26 yards against the Broncos, and did not play after halftime.
