As the 49ers try to advance to a divisional-round date with the Panthers, one of their top pass rushers isn’t playing.
According to Erin Andrews of FOX, linebacker Aldon Smith is questionable to return to the game with cramps.
Cramps typically happen during games played in very warm weather. Apparently, they happen in very cold weather, too.
The game continues to get colder. It’s currently three degrees, with a wind chill of 13 below.
UPDATE 6:45 p.m. ET: Smith is now back, as evidenced by a sack of Packers quarterback Aaron Rodgers.
