ALLEN PARK -- The NFL can be a tough way to make a living sometimes. Just ask offensive linemen Leo Koloamatangi and Brian Mihalik.
One day, they learned they made the Detroit Lions' 53-man roster -- and in Koloamatangi's case, it was the first time he had ever made a 53-man roster.
And the very next day, they learn they've been cut.
Detroit made the moves Sunday to correspond with successful waiver claims for offensive lineman Andrew Donnal (Ravens) and cornerback Dee Virgin (Texans).
Koloamatangi was competing for a reserve job on the interior of the offensive line.
