Jacob Markstrom has been returned to the minors by Florida. The Panthers' AHL affiliate, the San Antonio Rampage, is locked in a 2-2 tie in their first-round playoff series against Chicago. Markstrom's addition to the lineup could help the team in Game 5's deciding match of the best-of-five series on Friday night. He was called up when Jose Theodore was unavailable to play in Game 6 due to injury, but Theodore will return for Game 7.
