WELL WELL FOR TARRANT
The former Ross County forward could even make a permanent switch to Fir Park after failing to make a major impression at Villa Park.
Colchester United were interested in the 22-year-old last season, and he earlier spent some time on loan with York City.
"He is a proven goalscorer and spent a couple of years with a big club," said Well boss Billy Davies.
"He is still under contract there and, at the moment, I am just delighted to get him up here and playing for us.
"If he scores a few goals, we will take it from there."
The proposed deal scuppers trialist Eddy Bembuana's hopes of earning a contract with Well, who enjoy a special relationship with Villa.
