After taking a couple of knocks in recent games, Barker could well be a doubt for the weekend clash with Bury.
Stags boss Peter Shirtliff told the Mansfield CHAD this week "Richie got a kick on the same dead leg he was already suffering with.
"But I think he will train tomorrow (Friday). He is a tough boy and I think he will want to play on Saturday."
On the plus side for the Stags, Simon Brown looks to be fully recovered and scored in the 2-0 home win over Swindon in midweek, and with Danny Reet still kicking his heels on the bench, there are still plenty of options in the scoring department.
