ORDER

CAROLYN K. DELANEY, Magistrate Judge.

Defendants in this pro se prisoner action pursuant to 42 U.S.C. § 1983 have filed a motion for summary judgment. (ECF No. 56.) Plaintiff has filed an opposition (ECF No. 60), and defendants have filed a reply (ECF No. 62).

On May 4, 2015, plaintiff's motion to compel disclosure of certain documents was partially granted (ECF No. 59), and plaintiff has had the opportunity to review those documents subject to a protective order (ECF Nos. 66 & 67). The court will permit plaintiff to file a supplemental opposition to summary judgment, not to exceed 10 pages, addressing the materials he reviewed pursuant to the June 10, 2015 protective order.

Because these materials are under seal for security reasons (ECF No. 63; see also ECF No. 66), plaintiff should indicate in the caption of his supplemental brief that it is to be filed under seal and include a copy of the instant order.

Accordingly, IT IS HEREBY ORDERED that:

1. No later than thirty days from the date of this order, plaintiff may file a supplemental opposition to summary judgment, not to exceed 10 pages, addressing the materials he reviewed pursuant to the June 10, 2015 protective order;

2. Plaintiff shall indicate in the caption of his brief that it is to be filed under seal and include a copy of the instant order; and

3. The Clerk of Court is directed to file plaintiff's supplemental brief under seal, as it concerns sealed materials per ECF No. 63.
