Bella-Kotchap, 23, returned to league action for Saints in a 4-0 defeat to Brighton at St Mary's, coming on to replace Jan Bednarek.
The German's long-awaited first-team opportunity only came after Juric had exhausted all other centre-back options, including midfielder Joe Aribo and left-back Welington.
Bednarek, Taylor Harwood-Bellis and Jack Stephens are available again, potentially harming Bella-Kotchap's chances of successive Premier League starts.

Juric believes Saints were at their defensive best when Bednarek and Harwood-Bellis played alongside each other, however, Bella-Kotchap remains an option.
"I think it's a process for Bella-Kotchap after two years. I think he played two games and we can be satisfied knowing that he didn't play for a long time," he told the Daily Echo.
"For him, it's important now that he can play from the beginning or get 20 minutes, 30 minutes. But now in this moment, I count on him."
Nigeria international Aribo has started at left-centre back in the last two games but can now return to midfield.
The Croatian has regularly called that position a problem but now has more natural options in Harwood-Bellis and Stephens available to him.

"It was the best option for us when we didn't have a left centre-back to put Harwood-Bellis there and I think when he played, he played really good.
"I think Aribo is a great guy. He gave me the possibility to play there and, of course, he can do it in one game or for 45 minutes but not every game.
"And I think it was my bad decision against Brighton to put him there again. The only thing I can say I did wrong was in that game."
