England fast bowler Ollie Robinson did not return after lunch against Sussex and is expected to undergo a leg test as Glamorgan take the game for a fourth day.
Marnus Labuschagne and Kiran Carlson hit Glamorgan centuries as they led by 141 for 499-5.
Labuschagne made 138 in his final season before starting work in Australia, and acting captain Carlson is on 187.
Robinson is the latest worry for England ahead of Tests against Ireland and the Ashes this summer.
He did not start again after bowling a no-wicket-over eight.
“He’s got a stomach ulcer and they’ll have a scan on Monday to see how he is,” Sussex coach Paul Farbrace told BBC Radio Sussex.
“We knew it was going to hurt yesterday so that’s why we cut him early this morning. He tried so hard and he stuck with it because he knew it was only one and it was going to be the day.
“It was really self-defense. There was no part to make it worse, and it’s walking that hurts more than running.”
Robinson is part of England’s 15-man squad to face Ireland at Lord’s on June 1, while James Anderson has also been included despite a chest injury.
Meanwhile, fellow Sussex and England paceman Jofra Archer is out for the rest of the summer, while Nottinghamshire’s Olly Stone will be out for several weeks with a hip injury.
In his first game of the Championship, Carlson outplayed his famous teammate, hitting 18 fours and two sixes to complete the four as he came close to victory as he took the game to Sussex.
Labuschagne hit 16 fours and four sixes but faced 244 balls as he combined steady defense with occasional aggression, adding 288 for the fourth wicket.
It was the best record for Glamorgan against Sussex, beating the previous record of 161 by Sir Viv Richards and Tony Cottey in 1990.
The weather and the cricket were at their best in the past as Robinson stepped up to the crease and Labuschagne dug in to start the rescue.
Spinner Jack Carson won the first day with a superb stumping from Oli Carter to remove Zain Ul Hassan who made his debut after a mature knock of 43 as a stand-in opener, only to pick up his back heel as he went for the sweep.
Sam Northeast fell lbw first ball as Carson turned one full, and the young Northern Irishman then had Robinson come in at the other end to pile on the pressure.
Carlson was dropped on Robinson for three and wasted a chance to return through the fingers of Carson on 21, while Labuschagne reached 50 with a six off left-armer James Coles.
The century partnership came just before lunch, and Glamorgan didn’t bother with the bat in the afternoon session as Robinson’s absence left Sussex’s attack short-lived.
The new ball did not impress and Carlson was particularly good against the spinners as Glamorgan added 153 runs in the second innings.
Labuschagne smashed a straight boundary off Carson after tea but fell to batting hero Coles who won the lbw shout with the first ball of the new spell.
Glamorgan were 53 ahead at the time, but Carlson and Billy Root added 63 before Root was caught at short leg for 26 from Coles to revive the home spirits.
Chris Cooke, who did not keep wicket due to a hip injury, saw out the last half hour with Carlson.
Glamorgan’s Marnus Labuschagne told BBC Sport Wales:
“It’s been a fantastic season so far (at Glamorgan) and we’ve played some really good cricket, but I’m disappointed. You can have a hundred on the board but it’s a bit frustrating that you can’t put us on the pitch. How can they win the game?
“(Friday) afternoon, when Ollie Robinson faced me, I really felt that my game was in a good place to defend and get into the ball, then there was a moment where I lost a little piece and came back. I’m happy with where my game is, I just want to make sure that the first morning of Test Championship (against India) that I have prepared for the tournament.
“Kiran played an amazing innings, very mature in his first game as captain and able to keep his head. I am proud of how he worked hard and made few mistakes.
“Our first priority is to drive ourselves to safety and a place where we can’t lose the game, so we can put some pressure on Sussex.”
