Davis originally injured running out a groundball to first. The injury appeared somewhat serious, as the first baseman could not place any pressure on his leg and had to limp off the field.
Team doctors performed an MRI on Davis Saturday. The MRI revealed patellar tendinosis, or Jumper's Knee, which is a degenerative condition of the patellar tendon. The finding was not considered too serious, as team officials told the media that Davis would not need to spend time on the disabled list.
The team originally listed Davis as day-to-day, but Buck Showalter considered playing the first baseman on Saturday. Davis tested out his right knee Sunday before the game, and felt comfortable enough to play first and hit fifth in the team's lineup.
Davis' return is important for Baltimore, as he has been their best offensive player so far this season. Entering Sunday, Davis was hitting .330/.431/.690, leading the team with nine home runs and 19 RBI's. His offensive production earned Davis AL Player of the Month honors for April.
