Hayes, 23, currently sits tied for 10th in AHL goalscoring (22) and fourth on the IceHogs with 39 points.
The 6-foot-6, 221-pound winger made his NHL debut for the ‘Hawks last year, scoring 5G-4A-9PTS in 31 games while averaging just over 10 minutes a night.
Montador, 33, recently received medical clearance from a concussion that plagued him since last season, and was subsequently placed on waivers Monday.
Today he cleared, allowing Chicago to send him to the American League for conditioning.
Montador signed a four-year, $11 million deal with Chicago prior to last season and got off to a solid start, racking up 14 points in his first 52 games.
He hasn’t played a competitive game since last March, so the hope is for him to get back into game shape while playing for Rockford.
