Robbie Crawford has joined Motherwell on loan until January.
The central midfielder arrives from Livingston, where he has made 26 appearances since moving from Ayr United in the summer of 2019.
“It was important we added competition for places in midfield,” manager Stephen Robinson said.
“Having lost Liam Donnelly to injury, and sold David Turnbull, we have been short in numbers in that area.
“With the number of games we are facing in the league, in Europe and in cup competitions, it was vital we increased our pool.
“He comes with Premiership experience and, along with Barry Maguire, brings competition to the midfield.
“Robbie is a player we’ve watched for a number of years. He gives us a bit of bite and tenacity. He has good quality on the ball and is more game ready than some of our younger boys, who have been unable to gain vital game time with no reserve games.
“Bringing in Robbie allows us the chance to put boys out on loan, particularly Jamie Semple, Harry Robinson, Ross MacIver and Dean Cornelius.
“They can gain vital experience doing that and hopefully come back fighting for a place, as we develop the next crop of young players.”
Crawford, 26, played 225 times for Ayr United after coming through the youth ranks at the club, before earning his move to the Premiership.
He will go straight into the squad for Sunday’s trip to Aberdeen in the Scottish Premiership, and the selection for the trip to Israel to take on Hapoel Beer-Sheva in the UEFA Europa League.
