The Pittsburgh Tribune-Review's Rob Biertempfel and later MLB.com's Greg Luca tweeted that Pittsburgh Pirates starting pitcher Jeff Karstens will continue his rehabilitation from hip and shoulder injuries with the Curve on Tuesday at Peoples Natural Gas Field.
The Curve play New Britain that day at 7 p.m.
Curve manager P.J. Forbes said nothing was set in stone, however.
"I can't confirm [that Karstens is pitching in Altoona]," Forbes said. "I have not gotten wind of that."
Prior to Thursday's game against Trenton, the Curve announced several roster moves but they were put on hold thanks to flight problems.
Altoona called up outfielder Evan Chambers, infielder Drew Maggi and infielder Stefan Welch from Class A Bradenton, but their flight was delayed in Philadelphia.
Maggi and Welch were added to the roster anyway to replace Miguel Perez, who went on the seven-day disabled list, and Greg Picart, who was assigned to State College. However, since the players were not going to make Thursday's game, Anthony Norman, who had been assigned to State College, was reassigned to Altoona to serve as a backup outfielder while Chambers was held off the roster.
Norman pinch hit in the ninth inning, drew a walk and scored one of the Curve's six runs during a rally that secured a 7-6 win over Trenton.
"It was good to be able to stay here and contribute to something so fun," Norman said. "I was excited to be a part of that."
Chambers will be added to the roster today in Norman's spot.
"It's a difficult situation for him, and the organization, because we hold [Norman] in high regard," Forbes said. "He's a pro, and he does whatever you ask him."
Welch is the highest regarded prospect of the three incoming players.
"Chambers is an outfielder who will earn his way into playing time," Forbes said. "He can spell Grossman when he needs a day.
"Maggi can bounce around the field at shortstop, second and left field. Welch will come in and bounce between third base and first base."
Curve first baseman Matt Curry is currently on the disabled list but is expected to return soon.
"We'll play Welch at third base, and we'll be mixing and matching," Forbes said. "We'll get the other guys at bats, but we're hoping he can continue what he started at Bradenton."
