Phillies first baseman Ryan Howard exited Monday's game against the Nationals with a left knee contusion. Howard took a throw off the knee in the top of the seventh inning, and left the game an inning later.
Prior to the injury, Howard was 1 for 3 with a game-tying solo home run in the second inning. it was his 23rd blast of the season.
Howard was seen leaving the ballpark on crutches and could miss at least a few games, according to Comcast Sports Net. The team has not provided an official timetable for his return, however.
