"I just want to come back for my senior season," Hill said on Sunday. "My first three years at LSU have been very enjoyable and I'm looking forward to another great year next season.
"Getting a college degree is important to me and I also wanted to be able to celebrate Senior Day next year with my mom on the field with me. By coming back, I'll be able to accomplish both of these."
Earlier this week Hill, a native of New Orleans, had submitted his name as an early entry for this year's NFL draft. Juniors who opt to put their name in for the NFL draft have 72 hours to change their minds and withdraw from consideration.
"We're obviously delighted that Marquise has decided to return to LSU for his senior season," Saban said on Sunday. "He's an outstanding leader on this team and he's a tremendous player for us on the defensive side of the football and we're just elated that he's coming back for another year.
"I think Marquise's decision, along with those of our other juniors who have decided to come back, shows the type of commitment to academics that we have at LSU. By coming back for their senior seasons, all of these players are now going to leave LSU with a college degree and that's something that I'm very proud of."
Hill started 13 games at defensive end for the Tigers this season, helping LSU rank first in the nation in scoring defense and total defense. Hill finished with 40 tackles, including 10.5 for losses and six sacks. He led the team with 24 quarterback hurries.
In three years with the Tigers, Hill has played in 38 games with 25 starts. He's registered 17.5 tackles for losses and 10 sacks for the Tigers to go with 108 total tackles.
