The former Gateshead player, who moved to the Scottish Premiership in 2016 and scored 14 goals in 86 games, was out of contract in the summer.

Bowman, 27, comes in to replace top scorer Jayden Stockley, who is set to leave after Exeter accepted a number of bids for the former Aberdeen forward.

"Ryan is industrious and unselfish and has been throughout his time here," Motherwell boss Stephen Robinson said.

"With the options we have in attack, it's my view that we need to change it up for the second half of the season and that's what we intend to do."
