Tromso moved up to seventh after a 1-1 draw at struggling Bodo/Glimt. Tommy Knarvik put Tromso ahead with just two minutes to go, but Stig Johansen levelled matters.
Glenn Roberts scored the only goal as Aalesund won 1-0 at IK Start while Fredrik Winsnes was the match-winner in Stromsgodset's 1-0 victory at Lyn Oslo.
Sandefjord and Lillestrom drew 2-2 while Rosenborg, already crowned champions, played out a goalless stalemate at Viking.
