This news comes shortly after the announcement that fellow DB Antonio Allen suffered a season-ending Achilles injury and was subsequently waived (Aug. 7).
Milliner, 23, recently returned to participating in camp after missing most of last season due to an Achilles injury. He was the Jets first-round draft pick in the 2013. Milliner has started 14 games in his career, totalling three interceptions and 21 passes defended. As with Devin Smith, this time scale puts Milliner on track for an early season return. With the depth the Jets have at the cornerback position, this injury - the latest in a long line of setbacks for the third year pro - could put Milliner's roster status in jeopardy, although perhaps the fact his salary for the next two seasons is guaranteed anyway helps his chances.
The PUP list is no longer an option for anyone who has been practicing, but the Jets could theoretically use the injured reserve with a designation to return. However, in order to do this with Milliner, he'd have to clear waivers first, so that's unlikely. That would not be the case with the rookie Smith, as long as he was waived after the first cutdowns.
