Henry helped Michigan State overcome a season-high 18 turnovers, contributing four giveaways himself. He also made desperately needed shots, connecting on 8 of 13 from the field while the rest of the team struggled to score until a late offensive surge.
Reserve Rocket Watts and Joshua Langford each scored 11 points for the Spartans, who led by just six points at halftime.
Rutgers center Myles Johnson, who had two points and seven rebounds, appeared to hurt his left leg late in the game. The Scarlet Knights were already without center Clifford Omoruyi, who has been out with a knee injury since a win over No. 13 Illinois two weeks ago.
Rutgers: Free throw shooting has been a problem all season. Coach Steve Pikiell acknowledged it is an issue that has to get better.
Michigan State: Henry led the way as coach Tom Izzo needs him to for a second straight game. He had a career-high 27 points when the Spartans ended a three-game losing streak with an 84-77 victory over Nebraska on Saturday night.
