21-6-10: Lincoln City have agreed a deal to sign winger Gavin McCallum on a two-year contract from Hereford United. McCallum was offered a new deal to stay with Hereford, but has opted for a move to their League Two rivals. The 22-year-old only joined the Bulls from Weymouth last summer and impressed in scoring eight goals in 27 League Two appearances. He notched both goals in Hereford's 2-0 win over Lincoln in February and also made his full debut for Canada last month. McCallum becomes the second player to agree his exit from Hereford on Monday after the club confirmed Darren Jones would be joining Aldershot.
