The German international has been ruled out since picking up an injury in pre-season but could make her return this Sunday at the Joie Stadium.
Jeglertz also confirmed Mary Fowler and Bunny Shaw’s availability after the former withdrew from international duty for personal reasons and the latter missed Jamaica’s second friendly against Mexico.

On Knaak, he said: “Rebecca is training well and is available for the weekend.”
And on Fowler and Shaw: “Yes, she [Mary Fowler] is available.
“[Bunny] was an agreement with them [the Jamaican FA] that she only played the first game. She’s definitely available.”
Unfortunately, this weekend’s 14:30 (UK) kick-off will come too soon for Sam Coffey, who is ruled out after picking up an injury in our 4-2 win over Arsenal before the international break.
Coffey was forced to withdraw from the United States’ camp over the break but returned to her home country to continue her recovery.
Jeglertz is hopeful that spending time with friends and family in the States will mean she returns with a fresh impetus: “No, Sam will not be available for this game. We’ll see how it turns out next week.
“There wasn’t anything she couldn’t do in the US that she couldn’t do here. We cleared it with our performance team, and it was good for her headspace too.
“She lives far away, so she’s come back as a happy player and also when she’s back on the pitch, she’ll be a better football player.”
Other notable absentees this season have been Vivianne Miedema, Sydney Lohmann and Risa Shimizu, with the boss providing a positive update on their respective recoveries.
German midfielder Lohmann and Japan full-back Shimizu are close to a return according to Jeglertz, while Miedema is now back on the pitch as she continues to work her way back to fitness from a knee injury, though she’s yet to rejoin full training.
While Jeglertz wouldn’t put a timeframe on their recoveries, he’s pleased with how they’re each progressing.
“She’s on her way,” he said of Miedema.
“Definitely there aren’t any dates said in her rehab, she isn’t there yet but she’s on the pitch again, not training with the team but at least she has the boots on again. I’m looking forward to having her back.
“Sydney and Risa are almost there, but let’s see how they are progressing next week.”
