The move was announced Wednesday prior to Buffalo's home game against the New York Islanders. Coach Lindy Ruff said Lalime is day to day after he was hurt in practice earlier this week.
Enroth was Buffalo's second-round pick in the 2006 draft. The Swede has gotten off to a slow start in his second American Hockey League season with Portland, Maine. He's 3-7 with a 3.9 goals-against average in 10 games.
He was previously called up by the Sabres last February, but did not appear in an NHL game.
