CHARLOTTE – If you’re hoping the Carolina Panthers find an answer to their quarterback problems in free agency, you’d better set your sights a little lower.
   With not much to choose from in the free agent market and the trade deadline gone, the Panthers will bring in former St. Louis quarterback Keith Null for a workout Tuesday and if all goes well they will sign him to be their No. 3 quarterback behind rookies Jimmy Clausen and Tony Pike. Earlier in the day, coach John Fox said no matter who the Panthers sign they aren’t going to know the system and aren't expected to play much.

   The 6-foot-4, 219-pound Null was the St. Louis Rams’ sixth-round pick in 2009 out of West Texas A&M, the same school that produced Carolina wide receiver Charly Martin.
   Null started the final four games of the 2009 season for the Rams, completing 73 of 119 passes for 566 yards with three touchdowns and nine interceptions. He threw five interceptions in his first career start, a 47-7 loss against Tennessee. The Rams cut Null before the season and he spent a few days on Jacksonville’s practice squad before being released.
   A native of Lampasas, Texas, Null started in two seasons for West Texas A&M, throwing for over 9,000 yards in his two seasons as a starter. He was awarded All-Conference honors as a junior and senior. His junior season Null threw for 4,134 yards with 41 touchdowns and 14 interceptions. In one game against Washburn he threw for 498 yards and six touchdowns. Null erupted with a huge season as a senior, finishing the season with 5,097 yards and 48 touchdowns with 15 interceptions.
   The Panthers don’t seem particularly thrilled with list of free agents on the market, a list that includes Oakland castoff JaMarcus Russell, Patrick Ramsey, Chris Simms, and Andrew Walter.
    There are other options in the UFL including former Panthers Josh McCown, but their contracts prevent NFL teams from signing them until after the season is over in three weeks.
   Along with McCown, the other quarterbacks currently in the UFL include Jeff Garcia, Daunte Culpepper and Brooks Bollinger. The Panthers could buyout the UFL contracts, but given their current record (1-7) that's unlikely to happen.
