Left knee injury forced Mullan out of DC match

When Brian Mullan was replaced by Kamani Hill to start the second half of Wednesday's loss at DC, the move may have come across as a tactical decision. However, as it came to be known following the match, at halftime Mullan informed the coaching staff that he injured his left knee after slipping near the United penaly area halfway through the first half, which caused the substitution.

Mullan will be further evaluated upon returning to Colorado. His status for Saturday's home match against Sporting KC (7 pm MT) at Dick's Sporting Goods Park remains unclear.

Until the second half Wednesday, Mullan had been on the field for all but six minutes of the Rapids' first 10 and a half games. He is one of five players to start all 11 matches so far and his three assists are tied  for most on the team with Martin Rivero.

The Littleton, Colo. native has appeared in at least 20 matches for the past 11 seasons, and in 290 regular season games throughout his 12-year career. He is third among active MLS players in career games played, behind teammates Tyrone Marshall (327) and Pablo Mastroeni (318).

Rapids players currently unavailable due to injury are Pablo Mastroeni (concussion symptoms), Ross LaBauex (hernia surgery), Anthony Wallace (Achilles surgery), Jamie Smith (ACL), Marvell Wynne (hamstring strain), and Omar Cummings (ankle sprain).
