Sheldon Keefe revealed the reasons behind Simmonds and Acciari's absences with the former being sick and the latter not available due to a strange and concerning injury. The Leafs are 50/50 on Simmonds' availability for their next game and indicated that they would make a decision later today.
Noel Acciari, on the other hand, hasn't suited up since the 26th of March in a game against the Nashville Predators and has been ruled out for both games this weekend - Saturday at Ottawa and Sunday versus Detroit - with a neck/whiplash injury.
Calle Jarnkrok, Auston Matthews, and Mitch Marner remained the top line at today's pracrice with Alex Kerfoot, John Tavares, and William Nylander rounding out the top-6. Michael Bunting, David Kampf, and Sam Lafferty formed the third trio, while Zach Aston-Reese was skating with Ryan O'Reilly - in a red non sweater and practicing with the team for the first since since March 4th - and Radim Zohorna on the fourth line.
With the Leafs having 8 able-bodied defenseman, look for another 11/7 formation if Wayne Simmonds is indeed ruled out.
