Kallgren will get the starting nod in Florida in Tuesday, David Alter of The Hockey News reports.
EDGE Analysis
Jack Campbell earned a win over Tampa Bay on Monday so Kallgren will start the second half of the back-to-back. The 25-year-old rookie is 4-2-1 with a .906 save percentage through seven career NHL games, but he's coughed up 14 goals over his last four appearances. Tuesday's matchup against the league's best offense will be his toughest test to date.
