The Indians return four of their seven champions from last year.
Jackson put together one of the most dominating performances in the history of the SEMO Conference wrestling tournament last year en route to a 15th tournament title.
The Indians had seven individual champions and had 11 wrestlers in championship matches while racking up 410 points. Josh Schumacher, Ben McMillian, Sean Gant and Kamden Rampley are all back after winning championships last year.
"This year's going to be a little tougher," Jackson coach Steve Wachter said. "It should be pretty tight."
Luke Rayburn, Jamie Schumacher and Justin Miller are coming off runner-up finishes, and Russell Brown finished fourth last year.
This year's two-day event will start on Friday at Poplar Bluff.
Rampley remains undefeated at 215 pounds so far this year, including a title at the St. Charles West Tournament over the weekend and at the Tiger Classic. In the most recent missouriwrestling.com rankings, Rampley was listed second in Class 4 at 215 pounds. Also making the rankings for Jackson were Josh Schumacher, No. 7 at 135 pounds; and Sean Gant, No. 6 at 152 pounds.
Tyler Yeargain is Central's top returning finisher after finishing second last year. Yeargain, ranked sixth in his weight class in the most recent missouriwrestling.com poll, won the 130-pound weight class at the Tiger Classic this year. Chris Griffith and Matt Latham both finished fourth at the tournament last year.
Kelly earned the top seed and a bye into the semifinals of the Scott-Mississippi boys basketball tournament, which begins today at Chaffee High School.

The Jackson girls basketball team should get a good idea where it stands among the state's elite Class 5 schools Saturday when it faces St. Louis power Incarnate Word at the Notre Dame Shootout.
