Roland Pryor, who was out of boxing for four years, will attempt to clear the biggest hurdle of his comeback campaign when he takes on Johnny Gant in a bout billed as the "D.C. Welterweight Championship" Wednesday night at the D.C. Armory.

Gant's fight, the feature is at six-p.m. The evening's first bout is set for 7:30.

Pryor, 33, appearing in the third bout since he resumed boxing last December after a four-year layoff, boasts a 30-5 lifetime record. In facing fellow Washingtonian Gant for the first time, Pryor will be taking on his toughest opponent. Gant, 42-11-3 with 23 knockouts, is ranked seventh in the world by the World Boxing Association.

Gant lost a 15-round decision to WBA world welterweight champion Angel Espada in Puerto Rico in 1975. In his last bout, on April 13 at Capital Center, scored a unanimous eight-round decision over Justice Ortiz of New York. On the same card, Pryor knocked out Greg Burch with a vicious right hand in the sixth round of their bout.

There also will be five "Battle of the Cities" bouts between Washington and New York fighters on the Gant-Pryor card. Tickets, ranging from $6 to $12 are on sale at several locations. More ticket information can be obtained by calling 582-4440.
